Here are some leaked pictures of the upcoming Sony Ericsson ST18i and CK15i. Word has it that the Sony Ericsson ST18i comes jam packed with the Google Android 2.3 Gingerbread OS, an 8-megapixel camera and a 1GHz ARM Cortex-A8 processor. The Sony Ericsson CK15i features a slider keyboard and a 3.3-inch (240 x 400) resolution display. Too bad, there is no official conformation from the company at this moment. Stay tuned for more updates.
